The image shows a cross-section of a tooth implant. The implant is made of titanium and is placed in the jawbone. The implant has a screw-shaped design that helps to anchor it in the bone. The implant is surrounded by bone and tissue, which helps to hold it in place. The implant is used to support a dental crown, which is a tooth-shaped cap that is placed on the implant. The crown is made of porcelain or zirconia and is designed to match the patient's natural teeth.
